Quasilocal inequalities for attractive gravity probe surface
Tetsuya Shiromizu, Keisuke Izumi, Hirotaka Yoshino +1
We discuss the local and quasilocal properties of the loosely trapped surface (LTS) and the attractive gravity probe surface (AGPS), which have been proposed to characterize the st…

Initial data for a black string and a Kaluza-Klein bubble: Space-dependent compactification radius
Hirotaka Yoshino
As the first step to explore the nonlinear dynamics of an extra dimension in the Kaluza-Klein (KK) spacetime with black objects through numerical relativity, we generate time-symme…

Deci-Hz gravitational waves from the self-interacting axion cloud around the rotating stellar mass black hole
Hidetoshi Omiya, Takuya Takahashi, Takahiro Tanaka +1
Gravitational waves from condensates of ultra-light particles, such as axion, around rotating black holes are a promising probe to search for unknown physics. For this purpose, we…
